EVANSTON, IL. (CBS St. Louis) – According to a recent study out of Northwestern University, students learn more from an adjunct professor than from a tenured teacher.

David N. Figlio, director of Northwestern’s Institute for Policy Research wrote in the study that he found “strong and consistent evidence that faculty outside the tenure system outperformed tenured professors in introductory undergraduate classrooms.

Researchers also found that students who were less qualified academically did better in classes taught by faculty members that were not tenured.
